4. Burning monk

The flaming body of Buddhist monk Thich Quang Duc is shown on the pavement of a main intersection in Saigon, Vietnam. Other monks kneel with hands clasped in prayer. The elderly monk set fire to his clothing and burned himself to death in protest of alleged government persecution of Buddhists. “No news picture in history has generated so much emotion around the world as that one,” then-President John F. Kennedy said.
